A moraine-dammed lake, occurs when the terminal moraine has prevented some meltwater from leaving the valley. When a glacier retreats, there is a space left over between the retreating glacier and the piece that stayed intact which holds leftover debris (moraine). Meltwater from both glaciers seep into this space creating a ribbon-shaped lake ...

Glacial lakes are formed after the melting of glaciers. These lakes are formed in depressions or holes created on the surface of the land by glacial erosion. When such depressions fill up with water, lakes are formed. The water in glacial lakes is usually sourced from melting ice left behind by a retreating glacier or rainfall. Landscapes containin...
Kettle Lakes
Kettle lakes are formed in depressions in glacial outwash plains. Such plains are formed by sediments deposited by the meltwater of glaciers, usually at the terminus of the glaciers. Glacial calving often leads to the formation of such lakes. When a detached mass of ice from the glacier gets embedded or partly lodged in the glacial outwash drift, the ice eventually melts to result in the formation of a lake. The depth of the lake increases with the greater accumulation of outwash sediments ar...
Tarns
A tarn is small mountain lake that is located in a cirque (a steep-walled amphitheater-shaped landform formed at the mouth of a valley glacier). In some places like Northern England, the term tarn is used in a broader sense to refer to all ponds in Northern England’s upland areas. However, in glaciology, it refers to a lake left behind by a retreating glacier. The process of overdeepening usually leads to the formation of these lakes. Tarns can be seen in the Tatras Mountains in Slovakia.
A paternoster lake refers to one of the lakes in a series of glacial lakes that are connected to each other by either a single stream or a network of braided streams. Recessional moraines usually lead to the formation of such lakes. The lakes are named so due to their resemblance to beads on a string or a string of rosary beads. Such lakes usually ...
This type of lake is formed when a terminal moraine acts as a barrier to the flow of meltwater originating from a glacier. As the water is unable to leave the valley, it accumulates to form a lake. A moraine-dammed lake usually appears in the shape of a ribbon. The Calafquén Lake in Chile and Lake Hāwea in New Zealand are examples of lakes of this ...

Jul 2, 2024 · Firstly we have moraine-dammed glacial lakes, referring to a water body between a moraine ridge and a glacier,. These can then be divided into three subclasses; end-moraine dammed lakes, lateral moraine-dammed lakes, and moraine thaw lakes 6. Moraine dammed glacial lakes are the second most common type of lake found globally, and also the most ...
Feb 15, 2022 · Here lies the Imja Tsho moraine-dammed lake in Khumbu Himal, Nepal. This lake has grown from a network of supraglacial melt ponds within two decades and is currently the subject of much research by the scientific community to establish the likelihood of moraine failure and the release of a Glacial Lake Outburst Flood (GLOF).
Moraine-dammed lakes are bodies of water that form when glaciers deposit debris, known as moraines, which act as natural barriers to block the flow of meltwater. These lakes typically develop in glacial valleys and can provide insight into past glacial activity, as well as influence local ecosystems and hydrology. Understanding these lakes helps connect glacial processes with landscape ...
Oct 14, 2022 · The dramatic mass loss of Tropical Andean glaciers under the influence of climate change has caused alterations in regional hydrological regimes, including development and expansion of glacial lakes, especially moraine-dammed lakes, supraglacial lakes and ice-dammed lakes. There is a broad consensus on Moraine-Dammed Glacial Lakes (MDGLs) to be commonly understood as potentially most dangerous ...
